This fix is based on a change made in DRILL-5546. As described in
DRILL-5830, the HBase part of that fix was a bit redundant. It turns out that
HBase, via the project rel improvements in DRILL-5546, already expanded the
wildcard into columns using the 'DrillHBaseTable.getRowType()' method. (You
understand the details better than I...)
I wonder if we can do the same for MapR-DB binary? That way, we have just
one common path for projection push down.
